Subject: [PATCH v8 3/7] Documentation: DT: PL011: hi6220: add compatible string for Hisilicon designed UART
Date: Fri, 29 May 2015 10:08:35 +0800 [thread overview]
Message-ID: <1432865319-20413-4-git-send-email-bintian.wang@huawei.com> (raw)
In-Reply-To: <1432865319-20413-1-git-send-email-bintian.wang-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
Hisilicon does some performance enhancements based on PL011(e.g. larger
FIFO length), so add one compatible string "hisilicon,hi6220-uart" for
future optimisations or workarounds works.
